SHUTTER QR DOOR.

Application inea August so, 192e. seriai No; 132,429.

This invention relates to improvements in shutters or doors of the general character shown and Adescribed in Letters Patent of the United States No. 1,492,420, dated April 29, 1924.

In curtains of this general character th major portion of the shutter or door is comrised of a series of' metal plates each `having horizontally disposed hooks at the lateral edge portions thereof embracing an adjacent plate and each having a downturned flange on its upper end and an upturned flange on its lower end providing each plate with top and bottom hooks adapted to enter and leave bottom and top hooks, respectively, when the plates of the shutter or door are lowered andraised relatively to one another in closing and opening the same.

The object of the present invention is to improve and strengthen the plates in the regions of their connections with one another and thereby render them more durable -andefcient when in service. y l

The invention consists of the elements and the combinations of them hereinafter described andclaimed. l

In the accompanying drawings illustrating the invention,

Figure 1 is a front view of a portion of a shutter or door embodying my invention.

Figure 2 is a vertical section through the same, on line 2-2 of Fig. 1. Y

Figure 3 is a front view, partly in section, of the left hand side of the meeting top and bottom portions of two `plates when the shuttertis inthe closing position.- l

Figure 4 is view similar to Fig. 3, showing one .plate slightly Vraised with relation to the other.

`Figure 5 isa horizontal section through aportion of the shutter, on line 5-5 of Fig. 3, showing by dot-and-dash lines, the

position of an additional rearward plate in the position itzoccupies when the shutter is in the Vclosed position. 4

Figure 6 is a vertical section through a portion ofthe shutter, on line 6-6 of Fig. 3. Fi re 7 is a side view of the parts shown in Fig. 3, as seen from the right hand side thereof. Y V y Figure 8 isa vertical section through `a portion of the shutter, on line 8-.-8 of Fig. 3. Figure 9'is a side view of the bottom portion' of two plates of the shutter when they tion, of the bottom portion of the left hand side of one of the shutter plates.

Figure 11 is a View similar to Fig. 10, with the block removed from the plate.

Figures 12, 13, 14 and 15 are top, front, rear and end views, respectively, of the block shown in Figs. 3, 4 and 10 of the drawings.

Referring to the drawings, the shutter or door comprises a series of plates 3 each having blocks 4 secured to the lower corners thereof and each having a down turned flange 7 on its upper end, providing a downwardly opening hook, and an upturned flange 9 on its lower end, providing an upwardly opening hook.

The blocks 4 on the respective sides of each plate 3 are` alike excepting that they are made right and left, and, therefore, a description of one will suffice for both.

Each block 4 comprises a body 1() having a horizontally disposed hook 11 formed thereon, all parts of the block being shaped The end portion of the flange 9ito which the block 4 is secured terminates, lat 14, inwardly of a vertical plane extending from the adjacent vertical edge of the body of the plate 2 at right angles thereto; and that portion of the block 4 which extends between such plane and the end 14 of the flange 9` is offset, providing a wall 15 which forms a cavity 16 between it and the body of the plate 2. This wall 15 also forms the inner wall or part of the hook 11and it extends in alinement with the plate flange 9v and forms, in effect, a continuationthereof.

The block 4 is provided with an extension 17 which forms the bottom wall of the cavity 16 and which also forms a continuation of the block body and a continuation of the bottom of the wall and the bottom of the block body'k 10 and itsextension 17 is made rounded and snugly fitted within the rounded bottom portion 18 of they plate 2 which connects the flange 9 with the main body of the plate and which extends beneath the block extension 17 from the vend 14 `of the flange 9 to the adjacent lateral edge of the plate 2 and forms a backing or support for the block l and itsextension .17.'

Vhen the shut-ter is in the lowered or closing position, thehoolrsformed-by the flanges 7 on the upper endsoft-he plates rest within the hooks lformed yby the flanges 9 on the Y klower ends ofthe plates sothateach plate 1s suspended from andsupported by the next adjacent plate above it; and, whentheshutter is in the raised or opening position the successive plates 2 occupy positionsback of one another.- `T he hooks 11 of the 'lateral edge Vportionsofl the next adjacent lplate infront thereof so that each platej2 may. slide vertically through the hooks 11 of the next' adjacent rearward plate when the entire shutter isrraised to the open position or lowered tothe closed position by raising andvlow-ering the .lowermostplate'Q of thel shutter.

hooks formed by the flanges 9 on the Vlower ends thereof successively, leaving the plates suspended from one another, asishown in Figs. 1j and 2. During the raisingo-fthe shutter tothe opening position, the fplates'v2. are raised successively one by the other from thebottom upwards; and, asvthey are .thus

.- raised,'thev blocks of each plate'larelbrought v-The upper flanges' 7 of the Ve'ndrportions which terminate, at 20, inward' ly of parallel *vertical planes which extend at right angles from the lateral edges 'of the4 A intoengagement with the forwardV arms ofr the hooks 11 of the next adjacent rearward plate, after such hooks enter the cavities 16Y Vformed bythe blocks 4 which engage the same, thereby causingieach plate .to `pick up the next adjacent rearward plate, as the bot-A tom of each -plate reaches the level of the next adjacent rearward plate. Y.

i 'bodies of the plates, andthe length of the' vflange 7 of each plate2 is less thanthe space between thebloclrs' 410i the next adjacent v rearward plate to permit the flange 7 to enter sis suchspace Vwhenfthel hook formedl by. the

flange 7 of eaehplatje enters the hook formed;l by the flange` 9 of the next adjacent rearward plate. A l I The lateral edge Vportions ofthe plates 2 vwhich slide through the hools 11 are folded the bloclrs l of each plate 2 embrace and are slidably engaged withV plates 2 4have back against the bodies of the plates, as clearly shown in the drawings, providing a reinforcing or double thickness for such edge portions to withstand wear and to stifen the plates.

The hooks yll are so proportioned and* related to theV lateral edge portions ofthe plates 2 that the sliding engagement ofthe hooks -11 with the edge portions will guide the hooks formed bythe flanges 7 on theV tops of theplates 2 into the hooks formed by the flanges 9 on the bottoms of the plates, when the platesarelowered, and will also guide the forward arms of the hooks 11 into thel cavities 16`when the plates 2 are raised.`

The yplates y2 may be advantageously formed of suitable blanks of sheet ironory sheet steel and the blocks 4 may be advantageously formed of forged steel. j
